Can't create a custom recipe that includes a syringe with anything other than "level 0" nbt

[pwydalt]

Our modpack has some custom recipes, however, whenever we try to add nbt to your syringes they're ignored.
As an example:
{
"type": "rftoolsutility:syringe",
"key": {
"P": {
"item": "rftoolsutility:module_template"
},
"S": {
"item": "rftoolsutility:syringe"
},
"f": {
"item": "mysticalagriculture:spider_essence"
}
},
"mob": "minecraft:turtle",
"pattern": [
"fSf",
"fPf",
"fff",
"nbt": level 1

],
"result": {
"id": "rftoolsutility:slowness_module"
},
"syringe": 1,
"neoforge:conditions": [
{
"type": "neoforge:mod_loaded",
"modid": "rftoolsutility"
},
{
"type": "neoforge:mod_loaded",
"modid": "mysticalagriculture"
}
]
}
Never works. We've tried several variations, and all of them just get level 0, which ufnortunately, is impossible to acquire, as once you hit a mob with the syringe you get at least 10 (level 1)
